2、a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps,we will be able to assemble a machine as complex as the human brain, and if we can we will. Itmay then take us a long time to render it intelligent by loading in the right software (軟件)orby altering the architecture but that too

3、will happen.I think it certain that in decades, not centuries, machines of silicon (硅)will arise first to rivaland then exceed their human ancestors. Once they exceed us they will be capable of theirown design. In a real sense they will be able to reproduce themselves. Silicon will have endedcarbons

6、lions of people, will be within our power.練習(xí)題：Choose correct answers to the question:what way can we make a machine intelligentA. By making it work in such environments as deserts, oceans or space.B. By working hard for 10 or 20 years.C. By either properly programming it or changing its structure.D.

7、 By reproducing it.does the writer think about machines with human-like abilityA. He believes they will be useful to human beings.B. He believes that they will control us in the future.C. He is not quite sure in what way they may influence us.D. He doesnt consider the construction of such machines p

8、ossible.word carbon (Line 4, ) stands for _.A. intelligent robotsB. a chemical elementC. an organic substanceD. human beingsrobot can be used to expand our frontiers when _.A. its intelligence and cost are beyond questionB. it is able to bear the rough environmentC. it is made as complex as the huma

10、ssibility ofmaking a machine with human-like abilityC. once we make a machine as complex as the human brain, it will posses intelligenceD. robots will have control of the vast, man-made world in space1.C 事實(shí)細(xì)節(jié)題。第1段末提到，使機(jī)器具有智能的方法有兩種，要么安裝合適軟件，要么改變其架構(gòu)，故C正確。2.A 觀點(diǎn)態(tài)度題。作者在最后一段提到智能機(jī)器人可為人類做很多好事，故他對(duì)機(jī)器人態(tài)度是肯定的，

11、故A正確，同時(shí)排除C。文中只是說(shuō)機(jī)器人會(huì)超越人類,但并未提到會(huì)控制人類，故B排除;D與第1段末的that toowill happen矛盾，故錯(cuò)誤。3.D 詞義理解題。文中提到硅將會(huì)終結(jié)碳的長(zhǎng)期統(tǒng)治地位，聯(lián)系上文可知，硅指的是智能機(jī)器人，再結(jié)合上文的機(jī)器人會(huì)超越人類，故可確定碳指代的是人類。4.A 事實(shí)細(xì)節(jié)題。第3段首提到，智能機(jī)器人能幫助開(kāi)發(fā)邊遠(yuǎn)地區(qū)的條件是intelligence. increase tomatch thatof humans和cost declines,A與此相對(duì)應(yīng),故正確。5. B 推理判斷題。綜觀全文，作者討論制作智能機(jī)器人的可能性及其影響，B所述與此相符。文中指出智

12、能機(jī)器人的自我繁殖就是設(shè)計(jì)自己，故A錯(cuò)誤;第1段指出在制作出與人腦一樣復(fù)雜的機(jī)器人后，還必須花很長(zhǎng)時(shí)間安裝軟件或改變架構(gòu)后才能使其擁有智能，故C錯(cuò)誤;D中的控制人造世界屬過(guò)度推斷，文中并未提及。The human brain contains 10 thousand million cells and each of these may have a thousandconnections.
